In addition, a cyan filter and an infrared filter are provided inside the connector connecting the optical fiber sensor so as to oscillate only the reception sensitivity of the light incident on the light-receiving part or the specific wavelength of the light irradiated from the light source. Compared to determine the structure of the valves of the water tank and waste oil tank automatically It relates to marine discharge waste oil contamination measurement system.

일반적으로 유조선의 내부에 있는 배출 폐유 오염도 측정시스템은 유조선의 기름을 하역한 후, 회항하면서 탱크 속의 남은 폐유를 물과 섞어서 규정된 오염기준 이하의 상태로 선박 외부에 배출하는 장비이며, 이때 배출되는 물과 섞인 기름의 오염도를 측정하는 것이 광섬유센서이다.Generally, the waste oil pollution measurement system inside the tanker is a device that unloads the oil of the tanker, and discharges the waste oil in the tank with water to discharge it to the outside of the ship under the specified pollution standard.

여기서 제 1광섬유센서(10)와 제 2광섬유센서(20)는 고정드럼(40)에 고정되며, 상기 고정드럼(40)의 안측에는 광원(11)과 수광부(21)가 내장되어 있는 구조이다.Here, the first optical fiber sensor 10 and the second optical fiber sensor 20 are fixed to the fixed drum 40, and the light source 11 and the light receiving portion 21 are built in the inner side of the fixed drum 40. .

이 때 상기 제 1광섬유센서(10) 및 제 2광섬유센서(20)는 폐유와 물이 섞여 나오는 배출로(210)에 설치되는데, 이를 위해 상기 각 광섬유센서(10,20)는 연결커넥터(30)를 통해 길게 연장되는 구조이다.(도 3에 도시)At this time, the first optical fiber sensor 10 and the second optical fiber sensor 20 are installed in a discharge path 210 in which waste oil and water are mixed. For this purpose, each of the optical fiber sensors 10 and 20 is connected to a connector 30. ) Is a structure that extends long through (see FIG. 3).

그리고 상기 제 1광섬유센서(10)와 제 2광섬유센서(20)는 배출로(210)에서 상호 대칭되게 수직한 방향에 고정된다. The first optical fiber sensor 10 and the second optical fiber sensor 20 are fixed in a vertical direction to be symmetrical to each other in the discharge path 210.

그리고 상기 제 1솔레노이드밸브(51)는 물탱크(221)의 제 1유로(220)에 설치 되고, 제 2솔레노이드밸브(52)는 폐유탱크(231)의 제 2유로(230)에 설치된다.The first solenoid valve 51 is installed in the first flow path 220 of the water tank 221, and the second solenoid valve 52 is installed in the second flow path 230 of the waste oil tank 231.

더불어 제 1유로(220) 및 제 2유로(230)에는 각각 폐유와 물을 펌핑할 수 있도록 펌프(240)도 설치되는 구조이다.In addition, the first flow path 220 and the second flow path 230 has a structure in which a pump 240 is also installed to pump waste oil and water, respectively.

The valve 51 and the second solenoid valve 52 installed in the second flow path 230 of the waste oil tank 231 serve to intermittently.

도 4는 도 2의 A부분에 대한 확대도이고, 도 5는 도 1의 광섬유센서의 내부 광섬유가닥의 교번부를 나타낸 구성도이며, 도 6은 본 발명에 따른 제 1광섬유센서와 제 2광섬유센서의 파손에 따른 광면적을 나타내는 개념도이다.FIG. 4 is an enlarged view of a portion A of FIG. 2, and FIG. 5 is a diagram illustrating an alternating portion of an internal optical fiber strand of the optical fiber sensor of FIG. 1, and FIG. 6 is a first optical fiber sensor and a second optical fiber sensor according to the present invention. Is a conceptual diagram showing the light area according to the breakage.

먼저 도 4에 도시된 바와 같이, 상기 제 1광섬유센서(10)와 제 2광섬유센서(20)는 물과 폐유가 배출되는 배출로(210)에 설치된다.First, as shown in FIG. 4, the first optical fiber sensor 10 and the second optical fiber sensor 20 are installed in a discharge path 210 through which water and waste oil are discharged.

광원(11)에 연결된 제 1광섬유센서(10)는 배출로(210)로 광을 조사하고, 제 2광섬유센서(20)는 폐유의 오염도에 따라 난반사 및 산란하는 광을 입사시켜 수광부(21)에 의해 광을 검출하게 된다.The first optical fiber sensor 10 connected to the light source 11 irradiates light to the discharge path 210, and the second optical fiber sensor 20 receives light diffused and scattered according to the pollution degree of the waste oil to receive the light receiving unit 21. The light is detected by.

이 때 상기 수광부(21)는 포토다이오드인 것이 바람직하다.At this time, the light receiving portion 21 is preferably a photodiode.

그리고 상기 제 1광섬유센서(10) 및 제 2광섬유센서(20) 중 어느 하나의 연결커넥터(30)에는 포토다이오드의 수광을 용이하게 하기 위해 광원(11)에서 발진하는 광의 특정 파장의 세기를 최대화하는 시안필터(31)가 장착된다.(도 3에 도시)In addition, the connection connector 30 of any one of the first optical fiber sensor 10 and the second optical fiber sensor 20 maximizes the intensity of a specific wavelength of the light emitted from the light source 11 to facilitate the reception of the photodiode. Cyan filter 31 is mounted.

또한 상기 제 1광섬유센서(10) 및 제 2광섬유센서(20) 중 어느 하나의 연결커넥터(30)에는 가시광선을 차단시키는 적외선필터(32)가 부착되어 배출로(210)에서의 산란되는 빛의 량을 최소화시켜 줄 수 있다.(도 3에 도시)In addition, the connection connector 30 of any one of the first optical fiber sensor 10 and the second optical fiber sensor 20 is attached to the infrared filter 32 to block visible light is scattered in the discharge path 210 This can minimize the amount (see Figure 3).

그러므로 상기의 적외선필터(32)와 시안필터(31)를 통해 광량의 세기가 밝지 않아도 수광이 용이하여 광원(11)의 전력소모가 작은 장점이 있는 것이다.Therefore, even if the intensity of light through the infrared filter 32 and the cyan filter 31 is not light, it is easy to receive light has the advantage that the power consumption of the light source 11 is small.

한편 5와 같이, 본 발명의 제 1광섬유센서(10)와 제 2광섬유센서(20)는 충격에 의해 광섬유가닥이 손상되어도 전체 면적에 일정한 광이 조사되거나 입사될 수 있도록 중간부위에 광섬유가닥을 교번시킨 교번부(12,22)가 형성되어 있는 구조이다.On the other hand, as shown in 5, the first optical fiber sensor 10 and the second optical fiber sensor 20 of the present invention, even if the optical fiber strands are damaged by the impact to the optical fiber strands in the middle so that a constant light is irradiated or incident on the entire area The alternating parts 12 and 22 are formed.

만약 도 1과 같이 광섬유센서(9) 내의 광섬유가닥이 일정하게 배치되었을 때, 광섬유가닥이 파손되었을 겨우, 조사되거나 입사되는 광은 일정면적에 걸쳐 광이 나오지 않으므로, 수광부(포토다이오드)는 이를 인식하지 못하게 된다.If the optical fiber strands in the optical fiber sensor 9 are uniformly arranged as shown in FIG. 1, the light is irradiated or incident on the optical fiber strands, and thus the light receiving unit (photodiode) recognizes this. You won't be able to.

따라서 도 5와 같이 광섬유가닥을 교번부(12,22)를 통해 교번시키면, 도 6과 같이 광섬유가닥이 일정부위 파손된다 하더라도 광은 특정부위에서 죽지 않고 파손되기 전과 같이 광량 만이 작을 뿐 일정면적에 걸쳐 광이 나오므로 수광부(포토다이오드)는 이를 인식할 수 있는 특징이 있다.Therefore, when the optical fiber strands are alternated through the alternating portions 12 and 22 as shown in FIG. 5, even if the optical fiber strands are broken as shown in FIG. 6, the light does not die at a specific portion, but only the amount of light is small, as in the previous case. Since light comes out, the light receiving unit (photodiode) has a feature of recognizing this.

이하에서는 도 1을 참조하여 본 발명에 따른 선박용 배출 폐유 오염도 측정시스템의 동작에 관하여 설명하기로 한다.Hereinafter, with reference to Figure 1 will be described with respect to the operation of the marine waste oil pollution degree measurement system according to the present invention.

먼저 제 2광섬유센서(20)에 연결된 수광부(21)에 의해 실시간으로 검출되는 배출로(210)의 폐유 오염도 측정값에 의해 폐유의 오염도가 심해졌을 경우, 제어부(60)는 이를 비교 판단하여 배출로(210)의 오염도를 낮추기 위해 제 1유로(220)에 있는 제 1솔레노이드밸브(51)를 개방하고 제 1유로(220)에 연결된 펌프(240)를 동작시켜 물탱크(221)의 물 송출량을 증대시키거나, 제 2유로(230) 있는 제 2솔레노이드밸브(52) 개방하고 제 2유로(230)에 연결된 펌프(240)의 펌핑량을 조절하여 폐유의 송출량을 줄인다.First, when the pollution degree of the waste oil is increased by the waste oil pollution degree measured value of the discharge path 210 detected in real time by the light receiving unit 21 connected to the second optical fiber sensor 20, the control unit 60 compares and discharges it. In order to reduce the pollution of the furnace 210, the first solenoid valve 51 in the first flow path 220 is opened and the pump 240 connected to the first flow path 220 is operated to discharge water from the water tank 221. Increase or decrease the amount of waste oil discharged by adjusting the pumping amount of the pump 240 connected to the second channel 230 by opening the second solenoid valve 52 in the second channel 230.

또 다른 방법으로는 각 펌프(240)는 계속 가동시키고 각 솔레노이드밸브(51,52)의 부분 개방으로 가능하다.Alternatively, each pump 240 may continue to operate, with partial opening of each solenoid valve 51, 52.

아울러 폐유의 오염도가 약할 경우에는, 제어부(60)는 이를 비교 판단하여 배출로(210)의 오염도를 기준치로 높이기 위해 제 1유로(220)에 있는 제 1솔레노이드밸브(51)를 개방하고 제 1유로(220)에 연결된 펌프(240)를 동작시켜 물탱크(221)의 물 송출량을 감소시키거나, 제 2유로(230) 있는 제 2솔레노이드밸브(52) 개방하고 제 2유로(230)에 연결된 펌프(240)의 펌핑량을 조절하여 폐유의 송출량을 증대시킨다.In addition, when the pollution degree of the waste oil is weak, the control unit 60 opens the first solenoid valve 51 in the first passage 220 to increase the pollution degree of the discharge passage 210 to a reference value by comparing and determining this. The pump 240 connected to the flow path 220 is operated to reduce the amount of water discharged from the water tank 221 or to open the second solenoid valve 52 in the second flow path 230 and is connected to the second flow path 230. The pumping amount of the pump 240 is adjusted to increase the amount of waste oil discharged.
